ESC Q Format: Set Right Margin Comments: Sets the right margin to n columns in the current pitch. Settings made in the proportional mode are treated as pica. This command clears previous tab settings and all previous characters in. the print line. The minimum space between the margins is the width of one doublewidth pica character. Print head movement BS Format: Backspace Comments: Prints out data in the print buffer, then moves the print position one space to the left. Backspacing can be performed up to, but not beyond, the left margin setting. The BS code is also ignored if ESC a, 2, or 3 has been sent. In Epson mode, if this code is received immediately after graphics printing, the print position of subsequent data is moved back to the point at which graphics printing started. ESC $ Format: Set Absolute Print Position Comments: This sequence specifies the distance from the left margin that subsequent characters are to be printed, using this formula: total number of dots = nl + (n2 x 256). Each unit equals 1/60th of an inch. The sequence is ignored and the previous setting remains effective if the position specified is beyond the right margin. A-20 Command Summary

This sequence specifies the distance from the left margin that
subsequent characters are to be printed, using this formula: total
number of dots =
nl
+
(n2
x 256). Each unit equals 1/60th of an
inch. The sequence is ignored and the previous setting remains
effective if the position specified is beyond the right margin.
